  • solenoid 56 may operate as an arming solenoid for the other solenoids 72 , 74 , 76 , 78 and 80 , 82 .
  • solenoid 56 may be connected to the internal passages so as to act as an on/off valve for the entire assembly.
  • the supply ports for the manifold may comprise channels (not shown) formed in the undersurface of the manifold for attachment to a ported distribution plate or deck connected fluidically to the pump pressure circuit in the automatic transmission.
  • the present invention thus provides a unique electro-hydraulic manifold having electrically operated valves for controlling the pressure supplied to individual control ports with integrally mounted pressure sensors for providing an electrical signal in real time indicative of the pressure supplied to the control port and which manifold assembly and pressure sensors are sufficiently compact and robust to be mounted within the transmission and exposed to the hydraulic fluid therein.
